Sustainability Bonds are any type of bond instrument where the proceeds will be exclusively applied to finance or refinance Green Projects or Social Projects, and which aligned with the four core components of the GBP and/or Social Bond Principles (SBP).

The issuance of Sustainability Bonds has grown internationally since the establishment of the Sustainability Bond Guidelines in 2017. Sustainability Bonds that include green projects in the use of proceeds offer the same benefits as Green Bonds and are an effective tool to introduce private funds into Green Projects.

Green Bond Guidelines published in 2020 also apply to Sustainability Bonds that have green characteristics.
